Walmart Website Denied

Today I tried to refill a home delivery prescription at Walmart. The message-

An error occurred during a connection to www.walmart.com. Peer reports it experienced an internal error. Error code: SSL_ERROR_INTERNAL_ERROR_ALERT

The page you are trying to view cannot be shown because the authenticity of the received data could not be verified.

It has been out all day, and with Firefox and Chrome browsers.

Is this another problem such as Youtube last week?

Thanks
